Isothermal crystallization of PVDF using ultra-fast nano-calorimetry — •Evgeny Zhuravlev1, Arkadiusz Gradys2, Alexander Minakov1,3, and Christoph Schick11Institute of Physics, University of Rostock, Germany — 2Institute of Fundamental Technological Research, Polish Academy of Sciences, Warsaw, Poland — 3General Physics Institute, Moscow, Russia

By means of ultra fast thin-film nano-calorimetry, we were able to perform non-isothermal crystallization of poly(vinylidene fluoride) at cooling rates up to 100000 K/s. The new technique allows us to study samples of about 12 ng mass. Sample mass was estimated from measured heat capacity. At rates 12000 K/s and higher we were able to produce amorphous PVDF. At successive heating we observe so called cold crystallization. Isothermal crystallization of PVDF was investigated. Crystallization kinetics was studied at millisecond time scale. Experiments were performed from melt and from amorphous state of PVDF.
